public class ImageFilterView extends AppCompatImageView


An ImageView that can display, combine and filter images. Added in 2.0

Subclass of ImageView to handle various common filtering operations

ImageFilterView attributes

altSrc Provide and alternative image to the src image to allow cross fading
saturation Sets the saturation of the image. 0 = grayscale, 1 = original, 2 = hyper saturated
brightness Sets the brightness of the image. 0 = black, 1 = original, 2 = twice as bright
warmth This adjust the apparent color temperature of the image. 1=neutral, 2=warm, .5=cold
contrast This sets the contrast. 1 = unchanged, 0 = gray, 2 = high contrast
crossfade Set the current mix between the two images. 0=src 1= altSrc image
round (id) call the TransitionListener with this trigger id
roundPercent Set the corner radius of curvature as a fraction of the smaller side. For squares 1 will result in a circle
overlay Defines whether the alt image will be faded in on top of the original image or if it will be crossfaded with it. Default is true. Set to false for semitransparent objects

Summary

Public methods

void
draw(@NonNull Canvas canvas)
float

Returns the currently applied brightness

float

Returns the currently applied contrast

float

Returns the currently applied crossfade.

float

Gets the pan from the center pan of 1 the image is "all the way to the right" if the images width is greater than the screen width, pan = 1 results in the left edge lining up if the images width is less than the screen width, pan = 1 results in the right edges lining up if image width == screen width it does nothing

float

gets the pan from the center pan of 1 the image is "all the way to the bottom" if the images width is greater than the screen height, pan = 1 results in the bottom edge lining up if the images width is less than the screen height, pan = 1 results in the top edges lining up if image height == screen height it does nothing

float

gets the rotation

float

gets the zoom where 1 scales the image just enough to fill the view

float

Get the corner radius of curvature NaN = RoundPercent in effect.

float

Get the fractional corner radius of curvature.

float

Returns the currently applied saturation

float

Returns the currently applied warmth

void
layout(int l, int t, int r, int b)
void

Set the alternative Image Drawable used in cross fading.

void

Set the alternative Image resource used in cross fading

void
setBrightness(float brightness)

sets the brightness of the image; 0 = black, 1 = original, 2 = twice as bright

void
setContrast(float contrast)

This sets the contrast.

void
setCrossfade(float crossfade)

Set the current mix between the two images that can be set on this view.

void
void
setImagePanX(float pan)

sets the pan from the center pan of 1 the image is "all the way to the right" if the images width is greater than the screen width, pan = 1 results in the left edge lining up if the images width is less than the screen width, pan = 1 results in the right edges lining up if image width == screen width it does nothing

void
setImagePanY(float pan)

sets the pan from the center pan of 1 the image is "all the way to the bottom" if the images width is greater than the screen height, pan = 1 results in the bottom edge lining up if the images width is less than the screen height, pan = 1 results in the top edges lining up if image height == screen height it does nothing

void
setImageResource(int resId)

Sets a drawable as the content of this ImageView.

void
setImageRotate(float rotation)

sets the rotation angle of the image in degrees

void
setImageZoom(float zoom)

sets the zoom where 1 scales the image just enough to fill the view

void
@RequiresApi(value = Build.VERSION_CODES.LOLLIPOP)
setRound(float round)

Set the corner radius of curvature

void
@RequiresApi(value = Build.VERSION_CODES.LOLLIPOP)
setRoundPercent(float round)

Set the corner radius of curvature as a fraction of the smaller side.

void
setSaturation(float saturation)

sets the saturation of the image; 0 = grayscale, 1 = original, 2 = hyper saturated

void
setWarmth(float warmth)

This makes the apparent color temperature of the image warmer or colder.
